Methods

impl<N: ComplexField, D: DimSub<U1>> SymmetricTridiagonal<N, D> where
    DefaultAllocator: Allocator<N, D, D> + Allocator<N, DimDiff<D, U1>>, 
[src]

pub fn new(m: MatrixN<N, D>) -> Self[src]

Computes the tridiagonalization of the symmetric matrix m.

Only the lower-triangular part (including the diagonal) of m is read.

    self
) -> (MatrixN<N, D>, VectorN<N::RealField, D>, VectorN<N::RealField, DimDiff<D, U1>>) where
    DefaultAllocator: Allocator<N::RealField, D> + Allocator<N::RealField, DimDiff<D, U1>>, 
[src]

Retrieve the orthogonal transformation, diagonal, and off diagonal elements of this decomposition.

[src]

Retrieve the diagonal, and off diagonal elements of this decomposition.

pub fn diagonal(&self) -> VectorN<N::RealField, D> where
    DefaultAllocator: Allocator<N::RealField, D>, 
[src]

The diagonal components of this decomposition.

pub fn off_diagonal(&self) -> VectorN<N::RealField, DimDiff<D, U1>> where
    DefaultAllocator: Allocator<N::RealField, DimDiff<D, U1>>, 
[src]
